The National Weather Service says the Triangle has some chance of seeing severe thunderstorms this afternoon and evening, and storms that do develop could bring hail up to 2 inches in diameter, strong winds and even tornadoes.
Overall, however, the chance of any rain ranges from 20 percent to 40 percent across the area, forecasters said.
The chances for rain rise on Friday and Saturday, and the forecast posted this morning said thunderstorms were likely both days.
However, while storms are more likely those days, they did not appear to have the same potential for damage, according to the weather service’s Raleigh office.
Chatham County could see severe storms and hail tonight, but forecasters said they did not foresee tornadoes forming there.
ABC11 meteorologist Don Schwenneker said, “You may see a stray shower today,” but a “big line of storms and showers presses through” after 4 p.m. Friday.
Meteorologists said that a boundary between cooler and warmed air is behind the storm chances. That line was expected to drift south over the state today and bring cooler temperatures to the area, then get stuck over southern North Carolina.
Once that happens, it can become a path along which rainy or stormy weather can travel across the state, the weather service said.
Thursday’s highs were forecast to be in the upper 80s, but Friday’s were expected to be 20 degrees lower.
